The statement “the fastest way to cure cough” is not true and lacks scientific basis. There are many reasons for coughing, such as upper respiratory tract infections, gastroesophageal reflux disease, cough variant asthma. 1. Upper respiratory tract infections: mostly caused by viral infections, mostly self-healing. It can cause cough, nasal congestion, runny nose and other adverse symptoms. When the cough is severe, cough suppressants such as dextromethorphan can be used to treat the symptoms. The drug is contraindicated in women in early pregnancy. 2. Gastroesophageal reflux disease (GERD): The reflux of gastric acid into the gastric tube can irritate the pharynx and lead to cough. Omeprazole, magnesium aluminum carbonate, domperidone tablets can be used to treat the disease. Omeprazole should be used with caution in pregnant women. 3. Cough variant asthma: it is a special type of asthma, mainly manifested as irritating dry cough. It can be treated with inhaled glucocorticosteroids (e.g. budesonide) combined with bronchodilators (e.g. salbutamol). The use of the above medications should be under medical supervision. If you have a cough, you should go to the hospital in time, follow the doctor’s instructions to complete the relevant examinations, identify the cause of the disease, and carry out treatment under the guidance of the doctor, do not blindly believe in traditional Chinese medicine.
